In Section  we turn to the optimal transport problem. This is
ubiquitous in data science, where entropic regularization is a method of choice [1]}.
Geometrically, \(P_{A,b}\)  is a transportation polytope, and Segre varieties regularize
triangulations of products of simplices, as seen in Example REF .
Our contribution is an extension of this theory to unbalanced regime,
which was studied in [2]}, [3]}.
We formulate the discrete conic coupling in eqn. (REF ), in the spirit
of [4]}.
